Figure Lengend Snippet: a qRT-PCR results showed that SKL2001 treatment reduced fgfr4 mRNA levels by 31.4% in cultured blastema cells. Data were analyzed using an unpaired Student’s t-test and are presented as mean ± SEM, n = 5. The P value is shown on the panel . b qRT-PCR analysis of fgfr4 mRNA levels in the 1 mm tip portion of the distal blastema on days 8, 10, 12, 14 post-autotomy. Data were analyzed using one-way ANOVA followed by Dunnett’s post hoc test and are presented as mean ± SEM, n = 5. The P value is shown on the panel. c Representative immunofluorescence and EdU staining images showed FGFR4 (green) expression and proliferating cells (EdU, violet) in regenerated tissues on days 8, 10, 12, and 14 post-autotomy. The region between the solid and dotted lines represent WE. Scale bars represent 50 µm. d Normalized FGFR4 fluorescence intensity of z1-z5 on day 14. Integrated density was divided by the corresponding cell area and expressed as fluorescence intensity per unit area (arbitrary units, a. u.). The mean value of the control group was set to 1. Data were analyzed using one-way ANOVA followed by Dunnett’s post hoc test and are presented as mean ± SEM, n = 5. The P value is shown on the panel. e Schematic timeline for DMSO/IWP4 injection and sample collection. f qRT-PCR results showed a 67.2% increase in the mRNA levels of fgfr4 in the blastema after Wnt/β-catenin inhibition. Data were analyzed using an unpaired Student’s t -test and are presented as mean ± SEM, n = 5. The P value is shown on the panel. WE, wound epithelium. NC, negative control. qRT-PCR, quantitative reverse transcription.
Article Snippet: The Wnt inhibitor IWP-4 (2 mg/kg body weight, Cat# E0033, Selleck Chemicals, Houston, TX) or FGFR4 specific inhibitor BLU9931 (100 mg/ kg body weight, Cat# HY-12823, MedChemExpress, Monmouth Junction, NJ, USA) dissolved in 5% dimethylsulphoxide (DMSO) saline solution was injected intraperitoneally every other day from day 3 post-autotomy.
